Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific

SCALANCE XC100-4OBR

3.2
Purpose
Basic function
With the optical bypass relay SCALANCE XC100-4OBR, you can activate and deactivate
end devices in bus, star and ring structures without interrupting the communication between
other network components.
If an error occurs, the bypass relay bypasses the connected end device so that the
connection in the network is retained.
An end device is a device connected to the network via a bypass relay.
Normal operation
When the SCALANCE XC100-4OBR is supplied with power, the network interfaces are
connected to the end device interfaces of the bypass relay ①. The end device to which the
bypass relay is connected is therefore in the network.

Description of the device
3.2 Purpose
SCALANCE XC100-4OBR
Operating Instructions, 10/2013, C79000-G8976-C297-02 15
Bypass mode
If the voltage of the end device drops, for example due to a fault or during maintenance, the
voltage of the SCALANCE XC100-4OBR also drops. The monitoring voltage is no longer in
the set range.
The bypass relay then interconnects its two network interfaces within 10 ms. As result, the
connection to the end device that has been turned off is inactive and the bypass relay forms
the connection to the neighboring network components or bypass relays ②.
When you turn on the voltage of the end device and therefore of the SCALANCE XC100-
4OBR again, the two network interfaces remain connected until the end device is
operational. It is only after this startup time that the bypass relay connects the network
interfaces to the end device interfaces again.

3.2 Purpose
SCALANCE XC100-4OBR
16 Operating Instructions, 10/2013, C79000-G8976-C297-02
TAP function
In bypass mode, a SCALANCE XC100-4OBR with TAP function forwards the received data
not only to the neighboring network components. The TAP function has the effect that the
data is also sent to the end device. The end device receives and sends data as if it were
connected to the network. The data that the end device sends in bypass mode is not
forwarded to the network by the bypass relay.
With a bypass relay with TAP function, the end device can establish a link to the neighboring
network components in bypass mode.
Bypass relay with TAP function
If you use a bypass relay with TAP function in MRP or HRP rings, you can activate and
deactivate the connected end device without the redundancy manager initiating
reconfiguration routines in the ring.
Bypass relay without TAP function
If you use a bypass relay without TAP function in MRP and HRP rings, the redundancy
manager reacts when the connected end device is turned on or off again. The redundancy
manager enables the alternative (redundant) ring section and initiates the reconfiguration of
the logical communications connections.
Note
The insertion loss is lower with a bypass relay without TAP functi
on.

Installation guidelines
Note the information on the topic of redundancy in the configuration manuals of the
connected devices.
You will find the configuration manuals of the SCALANCE X switches on the Internet pages
of Siemens Industry Online Support
(http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo2&aktprim=99&lang=
en).
Operating the SCALANCE XC100-4OBR in an (R)STP network
Bypassing an (R)STP bridge
If you want to bypass an (R)STP bridge with a SCALANCE XC100-4OBR using the TAP
function, connect the (R)STP bridge to the (R)STP network only via the two ports of the
bypass relay.
Note
If you connect the (R)STP bridge with the (R)STP network via other ports, the TAP function
causes a network loop in bypass mode and communication in the network f
ails.
Bypassing the root bridge
If the root bridge of an (R)STP network is bypassed by a bypass relay, an alternative root
bridge is selected. By turning the root bridge on and off, the (R)STP network is recalculated.
If an (R)STP bridge is bypassed, the (R)STP section is longer and attenuation increases.
This changes the path costs.
Operating the SCALANCE XC100-4OBR in a redundant ring structure
Bypassing the redundancy manager
Within an MRP or HRP ring, a permanently configured redundancy manager must not be
bypassed using a bypass relay.
Note
If the redundancy manager is bypassed, this causes a network loop and the communication
fails.
Bypassing ring nodes
If the ring nodes are operated in the redundancy modes "MRP Auto Manager" or "Automatic
Redundancy Detection", any ring nodes can be connected and disconnected by the bypass
relay.
If the current redundancy manager is bypassed, another ring node takes over control of the
redundancy. If the redundancy manager changes, the logical communications connections
are reconfigured.

Areas of application
Redundant ring structure with SCALANCE XC100-4OBR with TAP function
By using the SCALANCE XC100-4OBR in MRP or HRP rings, ring nodes can be turned on
and off without the redundancy manager reacting to the topology change.
This, for example, allows maintenance to be performed without reconfiguration of the ring.
The communication of the ring nodes continues uninterrupted. This also avoids alarm storms
in the monitored network.
Due to the configurable startup time, end devices that have been turned off are returned to
the network when they are operational and have established the link to the neighboring
network components.

Redundant network with SCALANCE XC100-4OBR
By using the SCALANCE XC100-4OBR, network availability can be increased particularly in
networks that are not easy to access, for example wind farm networks.
If the bypass relay is connected before a network component, the network component can
be bypassed by the bypass relay if a problem occurs (e.g. power outage) and
communication in the network remains established.

Installation guide
Calculating the cable length
The maximum cable length between a SCALANCE XC100-4OBR and a connected network
component depends on the optical budget of the transceiver and the attenuation of the
bypass relay.
To calculate the maximum cable length, you need to deduct the attenuation values from the
optical budget of the transceiver.
The available budget is shown based on the example of the SFP transceiver (see section
"On the product (Page 8)", subsection "Accessories").
Note
The wall sockets in the device are specified as having an attenuation value of 0.3 dB. This
value must be deducted from the budget for each plug
-in connection.
To achieve a greater cable length, use transceivers with a higher optical budget, for example
transceivers with the designation LH instead of LD.
Transceiver
The SCALANCE XC100-4OBR is suitable for transceivers with the following properties:
●Multimode, 1300 nm, Fast Ethernet
●Single mode, 1310 nm and 1550 nm, Fast/Gigabit Ethernet
The SFP transceivers listed in the "Accessories" section have these properties. You can use
the SFP transceivers in IE switches with suitable slots.
You can also use IE switches in which the optical transceivers are already integrated.
Attenuation
The following factors influence the attenuation of the bypass relay:
●
TAP function
Bypass relay with or without TAP function
●
Mode
Normal or bypass mode
●
Variant of the bypass relay
single mode or multimode
The following use cases show the possible installation of the SCALANCE XC100-4OBR and
the resulting attenuation values.
